air compressor does not turn off at pressure, pressure relief valve lets off pressure at 180 lbs. this is worrying me and I am not going to use this until I get it fixed. any ideas. I am assuming the pressure switch is getting stuck, is this something that could be cleaned or needs replaced? it is about 2 years old maybe used 10 times for a few minutes (pump up tires etc) I was using it for the first time with impact gun to remove car tires when this happened.
it is this compressor

If I need to buy the switch is there a cheap source online?
